Morphology And Structure

The paper reports morphology and structure transitions of silicon carbide (SiC) nanowires during high temperature annealing; the as-prepared nanowires are in the form of SiC core and SiO2 shell. The transition temperature is about 1200 °C, 600 °C lower than that of SiC microfibers, and it starts with the formation of junctions of individual nanowires. The junctions grow into webs while the crystalline SiC cores of the nanowires oxidize. The growth and the oxidation eventually lead to the formation of an oxide film, when the transition completes. The thermal stability and the transition mechanisms of SiC nanowires are critical to their applications in high temperature environments.

Ysz Coating

Effect of La2O3 addition on thermal conductivity and high temperature stability of YSZ coating produced by EB-PVD was investigated. La2O3 was selected as an additive because it had a significant effect on suppressing densification of YSZ. The developed coating showed extremely low thermal conductivity as well as high resistance to sintering. Microstructural observation revealed that the coating had fine feather-like subcolumns and nanopores, which contributed to limit thermal transport. These nanostructures were thought to be formed by suppressing densification during deposition.
